Hall Longmore’s success is based on its proud history of delivering highest quality products to its markets.
Today the company owns manufacturing facilities offering modern industry leading equipment and process control for the production of large-bore welded steel pipes.

Hall Longmore uses the high frequency induction heating (HFI) process to manufacture pipes ranging in nominal diameter from 219 mm (8,58 inch) to 610 mm (24 inch).
Hall Longmore uses the submerged arc-welding (SAW) process to manufacture spiral welded pipe. This entails helically forming a hot-rolled steel strip and welding it both internally and externally to create a weld seam stronger than the parent metal.
